Terbutaline comes as tablets to take by mouth and as an aerosol to inhale by mouth. The tablets usually are taken three times a day. The aerosol is used as needed to relieve symptoms or every 4-6 hours to prevent symptoms. Terbutaline controls symptoms of asthma and other lung diseases but does not cure them. Continue to use terbutaline even if you feel well. Do not stop using terbutaline without talking to your doctor. Terbutaline is a relatively selective beta2-adrenergic bronchodilator. The pharmacologic effects of beta adrenergic agonist drugs, including terbutaline, are at least in part attributable to stimulation through beta adrenergic receptors of intracellular adenyl cyclase, the enzyme which catalyzes the conversion of adenosine triphosphate (ATP) to cyclic- 3′,5′- adenosine monophosphate (c-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mas
